Abstract

The confinement within carbon nanotubes (CNTs) improves the electrochemical reversibility of CNT-confined MnO2 nanoparticles and benefits their capacitive enhancement, which exhibit a specific capacitance of 225 F gāˆ’1 for the composites and MnO2 normalized capacitance as high as 1250 F gāˆ’1.
